SFH620A-3XG

Overview

The SFH620A-3XG is a single-channel optoisolator manufactured by Isocom Components 2004 LTD. It features an AC input configuration with an NPN phototransistor output, housed in a 4-pin DIP package. The device provides a minimum isolation voltage of 5300Vrms. Key electrical parameters include a maximum forward voltage of 1.65V, a typical rise time of 4µs, and a typical fall time of 3µs. The current transfer ratio ranges from a minimum of 100% to a maximum of 320%, with a maximum input current rating of ±50 mA.

Feature Summary

AC input capability for direct mains or alternating signal interfacing
High isolation voltage rating for robust circuit protection
NPN phototransistor output for standard logic interfacing

Applications

Logic-to-logic isolation in noisy environments
Line receiver circuits
Programmable current level sensors
Power supply digital programming
Computer and peripheral device interfaces

Procurement Notes

Verify the specific suffix '3XG' against official manufacturer documentation to confirm pinout and packaging details. Ensure compatibility with existing PCB footprints for 4-pin DIP configurations. Cross-reference safety certifications such as UL and VDE if required for end-use compliance. Confirm lead times with authorized distributors as manufacturing schedules may vary.

Selection Notes

Select this component when AC input driving is required without external rectification. The high CTR range supports reliable switching across varying temperatures. Verify that the 5300Vrms isolation meets system safety standards. Consider the 4µs response time for timing-sensitive applications. Ensure the NPN output interface matches the receiving circuit requirements.
